MALDI-TOF MS yields absolute molecular weights not relative ones. MALDI-TOF MS is a fast and versatile method to address challenges in the synthesis or quality control of polymers. Structural features such as repeating units (monomer), sum mass of the end-groups, average masses Mn and Mw are readily available. MS/MS analysis using MALDI-TOF/TOF instrumentation yields information about the block length of di-block-copolymers and masses of single end-groups.
